ABSTRACT:
Low boiling (C.sub.1 to C.sub.3) aliphatic hydrocarbons are obtained by passing a mixture of hydrogen and carbon monoxide at a volume ratio of about 45:55 to 60:40 at a temperature between about 350.degree. and about 500.degree. C. and a pressure of about 200 p.s.i.g. to about 10,000 p.s.i.g. at a volumetric hourly space velocity of about 200 to about 6000 in contact with a catalyst comprising an interspersed mixture of cobalt oxide, aluminum oxide, zinc oxide and molybdenum oxide. The catalyst comprises about 0.2 to about 2.0 weight percent of cobalt oxide, about 55 to about 95 weight percent of aluminum oxide, about 5 to about 15 weight percent of zinc oxide and about 2 to about 20 weight percent of molybdenum oxide. In preparing the catalyst, the cobalt, aluminum and zinc can be precipitated separately as the corresponding carbonates or hydroxides and then admixed with ammonium paramolybdate prior to calcination or two or more of the metals such as cobalt, aluminum and zinc can be coprecipitated as the carbonates or hydroxides at a controlled pH with sodium carbonate or ammonium hydroxide from the corresponding aqueous nitrate or acetate solutions and thereafter admixed with ammonium paramolybdate and any remaining metal salt, such as, for example, cobaltous nitrate or zinc hydroxide. The admixed salts of cobalt, aluminum, zinc and molybdenum are then dried and calcined.
